Application filed January 18. 1904: Eerial 1W0. 189,648.-

dolphin, Pennsylvcnia, have invented certain Improvements in Plate Cooling and Conveying Apparatus, of which the following-is a The object of my invention is to obol and dry heated plates of an 7 description While being conveyed from one point to another.

My invention. is especially adapted for use in connection with stereotypeplateslused for printing purposes-such, for instance, as the curved plates-made on an eutoplate or other casting-machine but it will be understood that my invention maybe appliedto the cooling of other plates without departingfrom my invention.

in the accompanying drawings, Figure 1 is a side View of my improved ep aratus, showing the parts in. diagram. ig. 2 is a sectional view on the line 2 2, Fig. 3 and Fig. 3

is a sectional view on the line 3-3, Fig. 2.

Heretofore stereotype-plates were cooled by ha-nd-dipping, after which theywere allowedto stdnd and drain until dry. By my invention 1 cm enabled to thoroughly cool the plates and then completely cry them while they are traveling from one point in e printing-office to another. y

Referring now to the drawings, A is an endless conveyor made up of two sets of chains o o, tied together by rods a o The conveyer Basses around Wheels on the driving-shaft around guides at t, and. into a tank D. In the tank are guide-rollers b 5 under which the conveyer passes, so that the y if the platestobe cooled are plates for printing newspapers then the conveyor extends from the casting-room to the press-room, and

plates carriedby the chainwill be submerged in the liquid in the tank and. cooled. At the opposite end of the tank the conveyer passes 'over a suitable guide at 1'2 then around a footovheel b. The return run the chain can be guided in any suitable manner.

Fingers c at the foot-wheel remove the plates from the conveyor.

In order to properly support the plates 01;,

which are oblong and curved in cross-section in the present instance, I provide carryingframes E, which are spaced at su1table'd1stenccs apart. These carryin -frarnes Ears pivoted to one cross-bar o o the chain, as shown in Fig. 2-, and are preferably slotted at e for the free passage of the cross-bar a, so

that the chain can have freedom in around guides heels or curved guides; .The frame in the present instance consists of two the shaft c, and these side members are connected together by a curved member e", which preferably conforms to the shape of the plate. Flanges e are formed at each while being transferred, cooled, and dried..-

I) is an. sir-pipe F, having suitable v erforations, so that when the plates leave t e tank ,the air will olow the Watcrfioih the plates and quickly dry them. While I have shown only one air-blast pipe, there may he more the deliver of air from this )ipe so that it will only (sliver. while the pate is in with it, and thus not unnecessarily waste the air.

Different devices may be designed to entometicelly control the air, the device shown the drawings consisting of s star-wheel a a The stem f carries a valve mounted in the valve-casing F, whiohcontrols the flow of aii tln'ough the pipe F. This pine has a series of perforations to allow for the escape of air. ,As the conveyor A travels, the. cross-bars o and a strike the teeth of the star-Wheelf and turn the air-valveF on and. off, so that air only escapes fromthe pipe F during the time the plate a: is passing under it.

The operation is as follows: For instsnce,

the tank is suitably situated between the two as it is removed from the casting-machine onto a carrier E at the receiving end, and as the conveyor travels the plate carried throughthe water in the tank l), and as it emerges fromthe tank it. is subjected to the blast of air, so as to quickly remove the water adhering to the plate. By the time the late reaches the press-room it is completely ried and ready to be mounted in position.

I claim as my invention 1. The combination of an endless conveyer,

than one, if desired. 1 preferably control points. The operator simply places the plate I Tss side memliers 0, each having a hearingon edge to hold the plate in a. fixed position Mounted at the delivery end of the trough.

mounted on a valve-sternf, the arms of the star-Wheel being 1n the path of the cros-rbars a tank through which the carrying-run of the conveyor passes, an air-blast pipe at the (lelivery end of the tank, means for automatically controlling the flow of air through the pipe so that a plate carried 0 the conveyor will pass through the tank an be cooled and then. subjected to a blast of air which is allowed to escape from the ipe While the plate 1 is crossing its path, su stantialiy as described.

2. The combination of an endless conveyor, plate-carriers mounted on the said-conveyor, a tank through which the carrier on the chain passes, an air-blast pi e at the delivery end of the tank, and a va ve for controlling the flow of air through the pipe, said valve being operated by the conveyor, substantially as described.

3. The combination in an endless conveyer,

ses eo of two chains, transverse rods connecting the chains, a plate-carrying frame pivoted to one ,of the cross-bars of the chain and slotted for the free passage of another cross-bar so that the chain can have freedom in passing-around guides, the said frame being curved for the reception of the late and flanged at each edge to hold the p ate in Mixed position, and a tank, with means for directing the conveyer through the tank, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
